Je suis coincé avec un problème qui survient parfois autour de unixODBC et freeTDS. J'ai un serveur Web CentOS où je suis installé les fichiers de configuration que:Parfois isql ne se connecte pas et tsql le fait
odbc.ini:
[XYZ]
Driver = FreeTDS
Server = X.X.X.X
Port = 1433

[ODBC]
;Trace = Yes

;ForceTrace = Yes
;Pooling = No
freetds.conf

et faire isql -v XYZ nom d'utilisateur mot de passe quand il ne se connectera pas il donne ce journal de suivi:

lorsque la commande tsql fonctionne ... que pourrait-on faire?
la version unixODBC est 2.2.11-7.1 et FreeTDS ne semble pas installé, mais il y est car il y a libtdsodbc.so présent dans/usr/local/lib ..
Je dois aussi dire que avec un redémarrage complet de la machine CentOS isql fonctionne bien ...
Que puis-je faire ou vérifier? Merci beaucoup d'avance!
Cheers, Luigi
